First, just start the bfip binary you created. You will be asked to enter the filename of the brainfuck sourcecode.

Second, start it with the filename in the commandline like this:

./bfip

There are two examples you can try:

helloworld.bf is a hello world program I took from Wikipedia

add.bf is a simple adding program I wrote myself

Q: I don't find a .exe! I can't start it!

A: There is no .exe file. Even if you use a Microsoft system, you should have a compiler installed. I recommend the gcc compiler. (The makefile produces a binary without .exe at the and.. but you should be able to rename it ;) )

Q:I started the add.bf example. But I can't use it! I can only enter one value!

A:The interpreter sees the "enter" key as a normal character. If you want to type two or more values, type them in one line. If you want to add 1 and 4 in the add.bf example, just type in 14 .
